| thaedge | I used a b234 lower end on my viggen rebuild. The only thing you have to be sure of is that the B234 is from a 1993 or newer TURBO 9000. The other thing is that you need to use the headgasket from the B234 and not he B235for compression issues. All in all, the B234 has stronger pistons and rods. It has also been debated that the actual block is stronger, but I don't know if I buy that, they are nearly identical except for a few extra screw holes. Let me know if you have any other questions. Basically use all the T7 ancillaries, and the B234 block and internals and you will be all set. | ||

Also, will the B235 pistons fit the B234? (stock bore) Many thanks! |

yeah they have lubrication problems but if you change the oil regularly and have the updated crank ventilation should be fine. also he was running 0w 50 oil thats a huge factor there. i have over 170000 on my engine with no sludge at all and no oiling issues. "knock on wood" |

 ).Also, decided to give it a try with the Amsoil 026 huuuge oil filter. So what else can be done? Can that sloppy oil pump be upgraded/changed? Slowly gathering bits of information, from over the Ocean... Lucian |

Even with a B234 block you will still be using the crap b235 oil pump (which is way worse than the b234's). If you really think that you have a lubrication issue I suggest trying to find a way to improve that aspect as well. |

| dcr99vig | what year is your car? mainly because if its t7 you will need to just swap everything off the block. sounds petty easy and that is my plan for my viggen, picked up a complete engine with a blown head gasket for 250. | ||

| 132417SAAB | although the car burned to a crisp kaylan (aerodynamic) was putting close to 500 whp on a stock b234 before she upgraded the internals | ||

B234 swap instead of B235 Well, after burning an stock 9-3 AERO B205 engine back in 2005, I recently managed to do it again...B235 engine almost fucked...the bearings on the crankshaft and engine block (3rd point, I think) were not enought oiled and died...taking with them a connecting rod! Initially, I thought the pistons are fucked! And after some initial tryes with JE, I went with Wossner Forged Pistons. But the main problem remains...I kill engines because of poor lubrication. Now, I have decided to switch to 5W-30 and a bigger oil filter, but the main problem remains: bigger torque and revs...bigger work on the joints of the engine. My mechanic, whom I 110% trust (he can make even a tank to go), said he will delete my balance chain/shaft (don`t know exactelly what he`s talking about). But then, he said: "If I would have known what you are going to demand from this tuned car, I would have searched for a B234 block! This idea, together with the ideea that the connecting rods of B234 are wayy better than the B235 connecting rods (actually, good as Verdi forged connecting rods) made me really think of a B234 swap instead of my B235 current engine. Well, guys, what do you think/advise? I understand the B234 engines are virtually indistructible, made from the very beginning reliable for more than 400 HP... beside the engine block, what else would I need (I already have the T5 cams). Will the pistons fit?, etc...(just to know what should I get into my budget)! standing by! Lucian (from over the Ocean)... P.S. valuable info! Quote:
